Linear Algebra 11L1: A Matrix Algebraic Expression for the Null Space

[abajabbajew]

Just to be clear, the 'elements' of the null-space of 'A' are the linearly independent set of vectors lying in the span of _any_ basis (any 'minimum spanning set') of 'A'. A situation of 'one A, many N'.

So isn't our matrix 'N' in some sense not an actual matrix, with determined coefficients, in the same way as 'A' is? Perhap writing 'A{N} = 0', borrowing from set notation (or some other means of making a distinction) would be desirable?
